Understanding Recirculated Air Heating Units

Recirculated air heating units work by taking the air from your space, heating it, and then redistributing it back into the rooms. This system can be particularly beneficial in maintaining a steady temperature and increasing energy efficiency. Here are some important considerations to explore:

Size Matters: Finding the Right Unit

The size of your recirculated air heating unit is paramount. A unit that is too small will struggle to heat your space effectively, while one that is too large may waste energy.

  • Calculate Your Space: Measure the area you need to heat. The general guideline is to require about 20 BTU (British Thermal Unit) per square foot of living space.
  • Consult a Professional: HVAC professionals can perform a load calculation to determine the ideal size for your specific needs.

Type of Heater: Choosing the Best Option

There are several types of recirculated air heating units available, each with unique advantages.

  1. Centralized Systems: Suitable for larger homes, these systems distribute heat through ductwork.
  2. Ductless Mini-Split Systems: Ideal for targeted heating in specific rooms, providing flexibility and reduced energy consumption.
  3. Portable Heaters: For temporary solutions or smaller spaces, these units can be easily moved.

Energy Efficiency Ratings: How to Read Them

When evaluating recirculated air heating units, energy efficiency ratings can significantly impact your utility bills.

  • SEER (Seasonal Energy Efficiency Ratio): For cooling efficiency, higher numbers indicate better performance.
  • AFUE (Annual Fuel Utilization Efficiency): For heating, look for units with AFUE ratings above 90% for efficiency.
  • Energy Star Certification: Units that meet the Energy Star criteria ensure higher energy efficiency.

Noise Level: Keeping It Comfortable

Noise can be a primary concern with heating units. When investing in a recirculated air heating unit, consider the following:

  • Sound Dampening Features: Some units come with features specifically designed to reduce noise.

Installation Costs: Budgeting for Your Purchase

Understanding the installation costs is crucial before committing to any unit. Here’s a breakdown of potential expenses involved:

  • Unit Price: Research different brands and models for comparison.
  • Installation Fees: Get multiple quotes from professionals to find the best deal.
  • Additional Ductwork: If your home lacks existing ductwork, this can greatly increase costs.

Common Problems and Solutions

Owning a recirculated air heating unit can come with challenges. Here are some common issues and practical solutions:

  • Inconsistent Heating:

    • Solution: Check for blocked vents or dirty filters, which can hinder air circulation.
  • Unpleasant Odors:

    • Solution: Regularly clean the system, as dust and debris can cause musty smells.
  • High Energy Bills:

    • Solution: Ensure that the unit is the right size for your home and that insulation is intact to prevent heat loss.

Conclusion

Choosing the right recirculated air heating unit can greatly enhance your home’s comfort and energy efficiency. By considering the size, type, energy efficiency, noise level, and installation costs, you can make an informed decision that best suits your needs. If you’re ready to upgrade your heating system or need assistance in selecting the perfect unit, consult with an HVAC professional today. Taking these proactive steps will ensure a warm and inviting environment for years to come.
